    Read the Wiki file on adding comets to the ssystem.ini file. Downloaded the Comet ZIP files. What I didn't see there was a way to add Comet ISON. Can this be done?

    TIA

    Try adding this to the ssystem.ini file

    [c2012s1(ison)]
    parent = Sun
    orbit_Inclination = 61.8916
    coord_func = comet_orbit
    orbit_Eccentricity = 1.000004
    orbit_ArgOfPericenter = 345.5129
    absolute_magnitude = 7
    name = C/2012 S1 (ISON)
    slope_parameter = 3.2
    lighting = false
    tex_map = nomap.png
    color = 1.0, 1.0, 1.0
    orbit_AscendingNode = 295.7319
    albedo = 1
    radius = 5
    orbit_PericenterDistance = 0.012499
    type = comet
    orbit_TimeAtPericenter = 2456625.29388889

    and search for it in stellarium as C/2012 S1 (ISON)
    Note:- These parameters may be out of date there could be a later set of orpital parameters
